Improved control is demonstrated for Managed Pressure Drilling (MPD) with the use of high-speed telemetry and physics-based models.

The control performance is evaluated in scenarios such as drilling, pipe connections, and kick attenuation. A physics-based drilling simulator, WeMod, is used for model identification and control performance evaluation. The control performance of the new nonlinear controller is compared to conventional controllers in various scenarios. Because of the interconnected multivariable and nonlinear nature of the drilling operation, conventional controllers show severe limitations. In a first scenario, the performance of set point tracking during normal drilling operation is compared. By changing the set point of the BHP, the conventional controller manipulates only the choke valve opening while the nonlinear controller moves choke valve opening, mud pump, and back pressure pump simultaneously. In a second scenario, a pipe connection of a typical drillpipe stand is demonstrated. The conventional controller is not able to regulate the BHP by adjusting the choke valve only. Although a linear version of the controller is able to exploit multivariable relationships, absence of the nonlinear relationships results in severe oscillation when the operational range is shifted outside of the training region. The nonlinear controller maintains a BHP within ±1 bar of the requested set point. A third scenario investigates the kick attenuation performance of conventional and nonlinear control algorithms. The nonlinear controller attenuates the kick within well control conditions, without requiring a well shut-in procedure.

i-DRILL integrated dynamic system analysis service uses predictive modeling to identify solutions that minimize vibrations and stick/slip during drilling operations and optimize BHA performance for a given environment. The IDEAS integrated dynamic design and analysis platform is used to quantify the vibrations and ROP for a given drilling system as a function of time by combining a bit rock-cutting model based on extensive laboratory testing with finite-element analysis of the bit and drillstring.
A wide range of equipment and conditions is evaluated to reduce harmful vibrations. Various combinations of drillbit options, drilling assembly components, drillstring designs, surface parameters, component placement, and overbalance pressures can be examined. The dynamics of the drilling assembly can be analyzed for formations differing in compressive strength, dip angle, homogeneity, and anisotropy to deliver optimal performance through formation transitions. This virtual drilling environment created by i-DRILL service integrates offset well data, surface and downhole measurements, and a thorough knowledge of products and applications in addition to taking detailed geometric input parameters and rock mechanics data into account.
Simulating the drilling operation to identify and evaluate the root causes of inefficient and damaging BHA behavior enables our engineers to objectively and precisely compare multiple approaches for correcting the problems via sophisticated dynamic analysis. This virtual testing of new technology and unconventional approaches eliminates the risk and expense of trial-and-error deployment at the rig while extending equipment life, minimizing failures, increasing ROP, improving hole condition and directional control, and decreasing overall drilling cost.

i-DRILL Integrated Dynamic System Analysis Service

Drill faster, longer, and more reliably by dynamically simulating the entire customized drillstring in a virtual drilling environment.
http://www.slb.com/idrill
i-DRILL integrated dynamic system analysis service uses predictive modeling to identify solutions that minimize vibrations and stick/slip during drilling operations and optimize BHA performance for a given environment. The IDEAS integrated dynamic design and analysis platform is used to quantify the vibrations and ROP for a given drilling system as a function of time by combining a bit rock-cutting model based on extensive laboratory testing with finite-element analysis of the bit and drillstring.
A wide range of equipment and conditions is evaluated to reduce harmful vibrations. Various combinations of drillbit options, drilling assembly components, drillstring designs, surface parameters, component placement, and overbalance pressures can be examined. The dynamics of the drilling assembly can be analyzed for formations differing in compressive strength, dip angle, homogeneity, and anisotropy to deliver optimal performance through formation transitions. This virtual drilling environment created by i-DRILL service integrates offset well data, surface and downhole measurements, and a thorough knowledge of products and applications in addition to taking detailed geometric input parameters and rock mechanics data into account.
Simulating the drilling operation to identify and evaluate the root causes of inefficient and damaging BHA behavior enables our engineers to objectively and precisely compare multiple approaches for correcting the problems via sophisticated dynamic analysis. This virtual testing of new technology and unconventional approaches eliminates the risk and expense of trial-and-error deployment at the rig while extending equipment life, minimizing failures, increasing ROP, improving hole condition and directional control, and decreasing overall drilling cost.

Microflux Identification of Ballooning & Breathing

http://www.weatherford.com/products-services/well-construction/secure-drilling/managed-pressure-drilling/microflux-control-system | The Weatherford Microflux Control System offers enhanced wellbore monitoring capabilities to detect a ballooning or breathing incident at its initial stage. Using the Coriolis meter’s real-time flow out data, the Microflux software plots flow out patterns while pumps are cycled—the pivotal factor in determining whether a wellbore is ballooning or breathing. The following video demonstrates Microflux’s ability to clearly and instantaneously identify wellbore ballooning and breathing during a standard connection in an offshore well at 14,918 ft. on bottom.

Automate Managed Pressure Drilling (MPD)

WiredDrillpipe (WDP) technology provides two-way and high speed measurements from bottom hole and along-string sensors. The data offered by WDP technology has maximum benefit when applied in an automation system or as a real-time advisory tool. Improved control is demonstrated for Managed Pressure Drilling (MPD) with the use of high-speed telemetry and physics-based models. Stabilizing and minimizing pressure within an acceptable bound leads to higher and more consistent Rate of Penetration (ROP). MPD control is challenging due to tight pressure windows and the nonlinearity of the choke and pump response on BottomHolePressure (BHP). This work demonstrates a new Hammerstein-Wiener nonlinear model predictive controller for BHP regulation in drilling. Hammerstein-Wiener models employ input and output static nonlinear blocks before and after linear dynamics blocks and thereby simplify the controller design. The control performance is evaluated in scenarios such as drilling, pipe connections, and kick attenuation. A physics-based drilling simulator, WeMod, is used for model identification and control performance evaluation. The control performance of the new nonlinear controller is compared to conventional controllers in various scenarios. Because of the interconnected multivariable and nonlinear nature of the drilling operation, conventional controllers show severe limitations. In a first scenario, the performance of set point tracking during normal drilling operation is compared. By changing the set point of the BHP, the conventional controller manipulates only the choke valve opening while the nonlinear controller moves choke valve opening, mud pump, and back pressure pump simultaneously. In a second scenario, a pipe connection of a typical drillpipe stand is demonstrated. The conventional controller is not able to regulate the BHP by adjusting the choke valve only. Although a linear version of the controller is able to exploit multivariable relationships, absence of the nonlinear relationships results in severe oscillation when the operational range is shifted outside of the training region. The nonlinear controller maintains a BHP within ±1 bar of the requested set point. A third scenario investigates the kick attenuation performance of conventional and nonlinear control algorithms. The nonlinear controller attenuates the kick within well control conditions, without requiring a well shut-in procedure.
